linux-core to free pci memory without freeing the structure. Linux-core
internals often create pci dma handle structures on the stack due to
the lack of a drm_local_map_t to store them in properly. Fix the
original drm_pci_free to actually free the dma handle structure instead
of leaking it.

There's two choices when fb is or isn't loaded as we treat ourselves as a
PCI driver in the latter case.
If we are a PCI driver, then register the suspend/resume functions
directly. If not, then we register as a sysdev and pick up the
suspend/resume actions and pump them down into a generic *power
function.
It'll be nice when this little mess is sorted out with regard to being a
real PCI driver ;-/

that a device absolutely is, absolutely is not, or may or may not be
AGP. Modify the i915 DRM to use this to force all i9x5 devices to be
"AGP" (even the PCI-e devices).

64-bit fixes. Bumped driver date and patchlevel.

two routines (one for G200 and one for G400) were replaced with static
const variables and a single function that returns the correct size.
The code to generate an error if the allocated WARP region is too small
was refactored from mga_warp_install_{g200,g400}_microcode to
mga_wrap_install_microcode.
mga_warp_microcode_size is global to the MGA DRM because it will soon be
used by code in another file.

is now allocated (and partially filled in) by the new
mga_driver_preinit function.
This allows the driver to detect the type of card (i.e., G200 class vs.
G400 class) on its own. The chipset value passed to mga_dma_init is now
ignored. This same technique is used by the radeon DRM.
As a result of this, mga_driver_pretakedown was converted to
mga_driver_postcleanup. This routine gets called in some other places
than might be expected, and it sets the dev_private pointer to NULL.
That little gem took over an hour to track down. :(

drm_addbufs. This makes the code more like the BSD code, and makes the
drm_addbufs_* functions callable in-kernel.

platform-specific drm_device_is_agp function. Added implementation of
this function the the Linux-specific portion of the MGA driver to
detect PCI G450 cards. Added code to the Linux-specific portion of the
generic DRM layer to not initialize AGP infrastructure if the card is
not AGP (this matches what already existed in BSD).
Bumped the driver date and the driver patch-level for MGA.
This mostly fixes bugzilla #3248. The BSD side still needs an
implementation of mga_driver_device_is_agp.

with IOMMUs and such. There is one usage of the forbidden vtophys()
left in drm_scatter.c which will be fixed up soon. This required a KPI
change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
keeps track of os-specific bits, rather than just passing around the
vaddr/busaddr/size.

flag DMA_QUIESCENT (typically the X server), but gets interrupted by a
signal. The locking IOCTL should then return an error, but if
DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it
has the lock. In addition The client waits for DMA_QUISCENT and
possibly DMA_READY without having the lock.

New PCI command parser. Moved from via_dma.c to via_verifier.c so functions
with similar functionality are close to eachother.
Moved video related functions to via_video.c, which might be extended in
the future, as new video functionality is added.
New device-specific generic IRQ IOCTL, similar to the general VBLANK IOCTL,
but with support for multiple device IRQ sources and functionality.
Support for Unichrome Pro PM800/CN400 video DMA commands in verifier and
PCI parser.
Support for Unichrome Pro PM800/CN400 HQV IRQs in the new generic IRQ
IOCTL.
Bumped minor. New version 2.6.0.

so we need to consult the EFI memory map before we try to set the write
combine attribute of a page. This patch will try to map a page write
combined if it's not an AGP page and the EFI memory map says it's ok,
otherwise it falls back to a regular, uncached mapping. Can someone
please apply this to the drm tree?

1. Initialize futex locks to zero on device init.
2. Remove some stray defines from via_drm.h
3. Prepare via_drm.h for drm client inclusion. The goal is to share a
common file with common definitions.
4. Sync shared / shared-core via_drm.h
5. Bump minor, because of the futex lock initialization.

affected vertex DMA buffer aging and client-side texture heap aging,
though with less fatal consequences. Bumped minor version and driver
